GPS RF Antenna Splitter

8224 Series

A GPS antenna splitter makes it possible to use a single GPS antenna and cable arrangement for multiple synchronization systems. Or, a splitter can enable a single GPS RF generator/simulator to simultaneously test multiple GPS devices. For example a 1:2 (1 input, 2 output) splitter eliminates the need for, and expense of, a second antenna and connected cable for installations with two devices with GPS receivers.

The antenna splitter can be used with any RF coax-based antenna and cabling system with type N connectors. These splitters operate across the GPS L1/L2 carrier frequencies and are compatible with other GNSS signals operating in these bands.

GPS Synchronization with Spectracom Equipment

Normally, one output of a splitter is set for DC pass-through to power the antenna from the Spectracom equipment to which it is connected. The other output leg is DC-blocked and has a 200 ohm DC load to ground, simulating a GPS pre-amp current draw. Splitters that are DC-blocked on all outputs require an external power supply to provide the 5VDC required to power the antenna. All DC-blocked versions have a connector for an external DC source. A compatible wall transformer can be supplied for 110, 220, or 240VAC with USA, UK or EU plug type. When external power is available, the splitter can also act as a signal amplifier.

GPS Testing by RF Generation/Simulation

Splitters that block DC power from all connected devices are compatible with Spectracom GSG series GPS simulators for testing multiple receivers simultaneously.
